Abstract

UN METODO PARA LA FABRICACION DE POLVOS DE CARBURO METALICO INCLUYE EL CALENTAMIENTO DE UNA MEZCLA DE REACTANTES SOLIDOS NO ESTATICOS DE UN OXIDO METALICO Y UNA FUENTE DE CARBONO A TEMPERATURA ELEVADA LA CUAL ES SUFICIENTE PARA PROVOCAR AL MENOS LA CARBURIZACION PARCIAL DE LA MEZCLA. EL CALENTAMIENTO REALIZADO EN UN ATMOSFERA NO REDUCTORA QUE TIENE UNA PRESION TOTAL DE AL MENOS UNA ATMOSFERA DURANTE UN TIEMPO SUFICIENTE PARA FORMAR UNA MEZCLA PARCIALMENTE CARBURIZADA. LA FUENTE DE CARBONO ES EMPLEADA A UN NIVEL EL CUAL ES MENOR QUE LA CANTIDAD ESTEQUIOMETRICA NECESITADA PARA PRODUCIR EL CARBURO METALICO. EL METODO PUEDE ADEMAS INCLUIR LA MEZCLA DE UN NIVEL SUFICIENTE DE UNA FUENTE DE CARBONO A LA MEZCLA PARCIALMENTE CARBURIZADA PARA FORMAR UNA MEZCLA AJUSTADA QUE TIENE UN CONTENIDO TOTAL EN CARBONO DE LA CANTIDAD ESTEQUIOMETRICA NECESITADA PARA FABRICAR EL CARBURO METALICO Y CARBURIZAR LA MEZCLA AJUSTADA EN UNA ATMOSFERA QUE CONTIENE HIDROGENO A UNA SEGUNDA TEMPERATURA ELEVADA LA CUAL ES SUFICIENTE PARA PROVOCAR QUE LA MEZCLA AJUSTADA FORMA EL CARBURO METALICO QUE TIENE UN TAMAÑO DE PARTICULA DE MENOS DE 0.2 MICROMETROS DE DIAMETRO.A METHOD FOR THE MANUFACTURE OF METALLIC CARBIDE POWDERS INCLUDES HEATING A MIXTURE OF NON-STATIC SOLID REACTANTS OF A METALLIC OXIDE AND A SOURCE OF CARBON AT HIGH TEMPERATURE WHICH IS ENOUGH TO PROVIDE AT LEAST PARTIAL CARBURIZATION. HEATING PERFORMED IN A NON-REDUCING ATMOSPHERE THAT HAS A TOTAL PRESSURE OF AT LEAST ONE ATMOSPHERE DURING A TIME SUFFICIENT TO FORM A PARTIALLY CARBURIZED MIXTURE. THE SOURCE OF CARBON IS USED AT A LEVEL WHICH IS LESS THAN THE ESTHEOMETRIC AMOUNT NEEDED TO PRODUCE METALLIC CARBIDE. THE METHOD MAY FURTHER INCLUDE THE MIXING OF A SUFFICIENT LEVEL OF A PARTIALLY CARBURIZED SOURCE OF CARBON TO THE MIXTURE TO ADJUST A TOTAL CARBON MIXTURE OF A NECESSARY CARBIDE ELECTRO-NECESSARY, NECESIZED, ESQUIOMETRIC, ATMOSPHERE CONTAINING HYDROGEN AT A HIGH SECOND TEMPERATURE WHICH IS ENOUGH TO CAUSE THE ADJUSTED MIX TO FORM THE METALLIC CARBIDE THAT HAS A PARTICLE SIZE OF LESS THAN 0.2 MICROMETERS IN DIAMETER.
